Bishop training spots

Ok. So I'm at 139, itching to hit 140. Thing is, outside of bosses, my training options kind of stink. I tried Minor Zombies, and though the spawn in the Dead Mine is much improved, I was only getting maybe 1-1.5% / 5 minutes, roughly 15% / hr. Clearly not viable based on other exp/hr reports.

Since I'm obviously not going to be able to find a Gallopera map on Bera, any other bright ideas?
